It can change on the fly the bitrate and adapt the image parameters accordingly. I say "in general" because sometimes I was not satisfied with their choices. They can adapt the resolution, framerate... to a chosen bitrate ( determined upon analyzing the network conditions). It can actually do 640x480 at 40 kbits/sec (if I remember correctly) !!! This I something I could not do with h.264 or any other available codec. Dragos
